update_config

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations; description only says 'Update', indicating mutation. No disclosure of side effects, permissions, or whether it merges or replaces config. Minimal transparency.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

One short sentence with parentheses. No wasted words, front-loaded. Appropriate length for a simple tool.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Tool is simple with 2 optional params and no output schema. Description covers basic purpose but lacks details on partial update behavior and success/error handling. Adequate but not thorough.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 0%, but description maps 'voice' to default_voice_id and 'playback speed' to playback_speed_rate. No additional format or constraints beyond schema types and defaults. Moderate value added.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

Clearly states it updates user config for voice and playback speed. Differentiates from sibling get_config, but 'config' could be more specific. Good verb+resource.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use or when not to. Implied via context but not explicit. No mention of prerequisites or alternatives.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
